So at the same purchase price and renos, using a little creative financing allows us to cut out "cash down" by more than half, which almost doubles our ROI!

We want to supplement our income from our full time jobs and make it easier for our wives to stay home with our children. 

Even if you don't cut yourself a large paycheck, your portion of the profits from your car lot is income.

Normally we'd have the grass cut during the first 1-2 days of taking ownership BUT, my pickup truck is in the shop and I can't fit the lawn mower in my car (or maybe I just don't want to - lol).

He cuts me a check and I either purchase or lose the auction. 

Or if you can cut expenses, the value goes up. 

I want to buy some land and put a few mobile homes on it while I use a portion for my construction business and rent a portion for horses to supplement my income.

You can bring up that if they take a full purchase price they will have a large tax bill from the sale, but with SF they will get steady monthly checks to supplement their SS and/or pensions.  

If things go well I'd even like to turn it into a business where I do this for other people, while getting a cut of their return.

My stove is like that now and I always have to remember to not have anything hanging over the edge.
